Title: Container filling machine valve system - has alternate switching of monitor air for fill check and sensor cleaning blowout air
IPC: B65B3/26
Filed: 1973-11-23
Abstract: The pneumatic control system is for container filling machines fitted with heads held in set relation to the container during valve controlled filling operations. The fill valve is opened via a valve operated supply line for compressed air, and the container level is scanned by a sensor tube connected to a pressure monitor line so that, when the fill level is reached, the monitor responds to back pressure by closing the fill valve via this supply line valve. A switching valve in the air supply line and in the monitor line admits pressure alternately to the pressure monitor line and to a blow-out line, used to clear the sensor tube. The valves forming the switching valve unit together with a valve in the blow-out line are held by springs in a first setting to admit monitoring air to the sensor tube until reversed by an additional valve, when the fill valve closes and so switches to the second setting to feed the blow-out air to the sensor tube. One of the switching valves has a relatively stronger opposing spring so that one valve in this unit is always switched over before the valve mounted in front has cleared the way for the blow-out air into the sensor tube.

Title: Tooth sharpener for milling cutter - has detector guiding cutter position during checking of tooth dimensions for comparison with reference values
Inventor: LAVERGNE
IPC: B24B3/04
Filed: 1976-04-02
Abstract: The sharpener is used when the milling cutter has teeth of various shapes. The tool detects the cutter tooth, the distance of the cutting edge of which to the centreline is the shortest. The cutting surface is brought in line with a reference plane, after which this cutting edge is sharpened. A store registers and stores electrical reference values which represents the distances of the first sharpened cutting edge to the centre line of the cutter. The cutter is then rotated to bring the next identical cutter tooth to the grinding position. This tooth is sharpened while the dimensions are checked with the stored data of the first tooth. The cycle is repeated for all similar teeth. The edge of a cutting tooth of different shape is determined after all the teeth of the first set are ground.
